# Solution

The fractal unit of completed work

Layer: Infrastructure · Category: Data Structures

## Mechanism

A recursive [Work](https://mindscape.world/scapes/bootstrap/Work.md) unit that contains an output [Artifact](https://mindscape.world/scapes/bootstrap/Artifact.md), provenance identifying its creator and creation time, and a reference to its originating [Task](https://mindscape.world/scapes/bootstrap/Task.md). Composite solutions also record a component [Tree](https://mindscape.world/scapes/bootstrap/Tree.md) of the sub-solutions used to generate them; omission of that tree denotes a leaf. It is the verifiable output container validated against the task's acceptance criteria.

## Invariants

- Immutability: Once finalized, [Artifact](https://mindscape.world/scapes/bootstrap/Artifact.md) and Provenance cannot be modified.
- Provenance attributes the Solution to its Creator and the time of creation.
- Where the Creator is untrusted, attribution is cryptographically signed.

## Preconditions

- [Artifact](https://mindscape.world/scapes/bootstrap/Artifact.md) generated
- [Task](https://mindscape.world/scapes/bootstrap/Task.md) ID is valid

## Postconditions

- Solution sealed and ready for transport

## Failure modes

- Orphaned [Artifact](https://mindscape.world/scapes/bootstrap/Artifact.md): Solution does not reference a valid [Task](https://mindscape.world/scapes/bootstrap/Task.md) ID.
- Broken Lineage: a composite Solution references a sub-solution whose verification fails ([Chain](https://mindscape.world/scapes/bootstrap/Chain.md) of custody broken).
- Schema Violation: [Artifact](https://mindscape.world/scapes/bootstrap/Artifact.md) data does not match acceptance criteria type.
